Accuracy is ±1% of FS at calibration temperature and pressure. The meter’s automatic sensor zero offset adjustment can be activated locally with a maintenance push button or remotely via digital interface. Digital command technology starts, reads, or saves the current auto zero value. Additional XFM features include aluminum and stainless steel models, digital interface RS485, RS231 (with or without LCD displays), and optional Profibus DP (with I&M functionality). Also available are programmable totalizer, high/low flow alarms, self-diagnostic tests, 23 different volumetric flow or engineering units and internal or user-specific K-factors.
